“What is cloud computing?”
This is the buzzing sound around nowadays & it remarks the popularity of cloud computing. Cloud computing is a topic that many find confusing though, it isn’t. Everyone have used a sort of cloud computing when using services like Gmail, Hotmail or Yahoo Mail based on Web-based email services. In the short and sweet terms, cloud computing simply means accessing programs, data and storing it over the internet without using your computer’s hard drive. It is a type of internet based computing serving you with the above factors through internet. It can be called as virtual service.
We often use the cloud symbol to represent the internet flowcharts & diagrams, and this is where the name cloud computing come from. It is also a metaphor for “the internet.” Cloud computing services are broadly parted into categories namely, Software-as-a-Service (SaaS), Infrastructure-as-a-Service (IaaS) & Platform-as-a-Service(PaaS). The cloud services have some unique characteristics thereby making them different from traditional hosting known to us. It had always been expensive and too complicated to run traditional business applications owing to the variety of hardware and software required to run them. These headaches can be eliminated with cloud computing as service providers manage the hardware and software resources.
Cloud computing services are fully commercial and sold on demand to users. Users have the flexibility to use it as per necessity i.e, can resort a small amount of the service, to the maximal as and required at any time. Users simply need to have a computer and internet connection to use the cloud computing services as they are fully managed by the service providers.
Why Cloud computing is better?
The main accelerators of cloud computing can be the accessible high-speed internet and indicative innovations in virtualization and distributed or shared computing. Cloud computing helps you to save on money as they cost less. Companies need uptime guarantee which is well serviced in a cloud computing environment. The ultimate aim of cloud computing is to deliver high-performance computing or traditional supercomputing power in areas such as financial portfolios, apply information mainly personalized, to resort data storage or to summon immersive PC games with high power. To serve the purpose, cloud computing deploy networks of large groups of servers with virtualizations to provide maximal power. The deployed servers typically have specialized connections to spread and serve data-processing chores across them. This nature eventually comes under shared IT infrastructure consisting of large pools of system thereby interlinked.
Difference between Public and Private Cloud?
Public or Private, the two forms of cloud computing. A cloud can be public, thereby selling services to anyone on the internet as like the Amazon Web Services. Public cloud may be freely available to the general public or charged on pay-per-usage term. Public clouds are easy and inexpensive, because user pays only what is used. Also, the setups are managed by the service provider.
Private cloud is also called as corporate cloud or internal cloud consisting of proprietary computing architecture to provide hosted services to a defined or limited number of people. As the virtualization and distributing computing have advanced it has enabled datacenters and corporate network administrators to be cloud computing service providers. Private cloud aims at providing enhanced security and more control over the company’s data as the
setup is done behind the firewalls.
Both public and private cloud serve the purpose of providing access to computing and IT services.
How Cloud computing is Classified?
Classifications of cloud can be done according to the types of services offered. Infrastructure-as-a-Service (IaaS) – This consists of purchasing or buying access to computing capacity over the internet such as storage or servers.. IaaS often deploys the technique of virtualisation thereby empowering the users to create their own virtual computer. This easily makes the users specify the applications, software and operating system they want to deploy in the cloud. It mainly gives users the advantage of staying free from the worry of buying and running hardware and pay for what is used.
Platform-as-a-service (PaaS) – This is meant for developing applications that use web-based tools, so they run in a software environment (i.e. a platform) on provider’s infrastructure. Google Apps is the best example of PaaS.
Software-as-a-service (SaaS) – It defines using a total application running on someone else’s system. Web-based email and customer service management systems are better defined examples of SaaS.
Why Cloud computing is future trend?
Cloud Computing has started gaining mass appeal in corporate data centers, small and medium size business and driving more response from users. The market observers believe it to be the future of computing owing to its peerless features and cost saving advantage. Ample of businesses have started using cloud computing as they turn out to be cheaper, easy to use, faster and hassle free in regards to maintenance. A mass percentage of web hosting
companies have started providing the cloud computing services to ensure better uptime.
Deploying cloud computing ensures more productivity and profitability as it complete tasks faster. Even general internet users are favoring the cloud computing as the increase percentage of Google Docs, Dropbox denotes it.
